<description>
|
|
<p>
|
|
IOActive discovered an error in the Mono.Math.BigInteger class, in the
|
|
reduction step of the Montgomery-based Pow methods, that could lead to
|
|
a buffer overflow.
|

|
<impact type="high">
|
|
<p>
|
|
A remote attacker could exploit this vulnerability by sending specially
|
|
crafted data to Mono applications using the BigInteger class, which
|
|
might lead to the execution of arbitrary code with the privileges of
|
|
the user running the application (possibly root) or a Denial of
|
|
Service.

</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Mono users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-lang/mono-1.2.5.1-r1"</code>
